Relationship between salivary biomarkers and performance in long-distance running
Purpose: The aim of the present study was to evaluate the salivary cortisol and alpha amylase levels in response to long-distance running according performance variables as accumulated distance, total time and velocity of running in athletes. Methods: Eight sportsmen (aged 21±2 years; Body Mass Inde...

| Sumario: | Purpose: The aim of the present study was to evaluate the salivary cortisol and alpha amylase levels in response to long-distance running according performance variables as accumulated distance, total time and velocity of running in athletes. Methods: Eight sportsmen (aged 21±2 years; Body Mass Index 20±1 kg/m2) completed a total of 259 km in 17 hours, throughout 3 days. The distance, total time run, and velocity during running were computed, and saliva samples were collected in the morning and at night for 3 days. Pearson correlations between variables were performed. Results: The range of distances was ≈ 7 to 54 km, and total time per run was ≈ 32 to 198 minutes, and the velocity of run was 13 to 16.5 km/h. Pearson correlations showed positive relationships between salivary cortisol and distance (r=0.81, p<0.01), total time running (r=0.77, p<0.02) and velocity during run (r=0.89, p<0.002). In addition, no correlations were observed to salivary alpha amylase. Conclusions: Based on this result, the accumulated distance, total time and velocity of running exhibits positive correlations to salivary cortisol, but not to salivary alpha amylase. This data shows that an endocrine response is continuously demanded in long distance running. |
